摘要： PURPOSE: To provide a compact device of which direction of force can be changed by a method wherein a piston acting also as a cylinder provided with an output rod is fitted in an outer cylinder, a piston provided with the input rod is fitted in the piston also acting as a cylinder and either a gas of a liquid is filled in a space between the outer cylinder and the piston.
CONSTITUTION: A piston 11 also acting as a cylinder is fitted in the outer cylinder 9 and then the piston 10 is fitted in the piston 11 also acting as a cylinder. The piston 11 also acting as a cylinder is provided with the output rod 18 extended therein and with the communication hole 12. In the piston 10 is extended the input rod 19. Oil is flowed into the chamber A enclosed by the piston 10 and the outer cylinder 9. When the input rod 19 is pulled in a direction indicated by an arrow P, the force causes the piston 11 also acting as cylinder to be moved in the direction P' and then the transmission of the force is performed with a ratio of each of the ratio of pressure accepting areas between the piston 10 and the piston 11 also acting as the cylinder.

摘要： PURPOSE:To raise the strength of a joint by providing diaphragm plates to the insides of the main pipe and branched pipes in a face-to-face manner in the joint where plural branched steel pipes as braces are gathered in the main steel pipe. CONSTITUTION:In a joint where plural branched steel pipes 2 are gathered in the main steel pipe 1, diaphragm plates 3 and 4 are provided to the insides of the main pipe 1 and the branched pipes 2 in a face-to-face manner, and a bracket 5 to ease the concentration of stress on the diaphragm plates 3 and 4 and the same faces as them is provided to the outside of the connecting portion between the main pipe 1 and the branched pipes 2. Furthermore, ring frames 6 and 7 are provided to the ends of the diaphragm plates 3 and 4, and a ring frame 8 is provided to the inner crossing portion between the main pipe 1 and the branched pipes 2. Thus, the transmission of force can be smoothly attained by the action of the diaphragm plates 3 and 4, and the concentration of stress can be eased by th actions of the bracket 5 and the ring frame 6-8.

摘要： PURPOSE:To improve self-priming performance of an axial piston pump motor, by feeding high-pressure fluid in a cylinder of a cylinder case to the sliding surface between a port plate and the cylinder case, and thereby eliminating tilting moment of the cylinder case and uneven contact of the cylinder case to the port plate. CONSTITUTION:A connecting passage 14 is formed in a cylinder case 2 in the manner that it is extended from an inclined surface 15 on the side of a cylinder 4 formed owing to the pitch difference d1-d2 of a suction and a discharge ports 2a to the sliding surface of a thrust pad 13 formed at the end face of the cylinder case 2. Through the connecting passage 14, high-pressure fluid in the cylinder 4 is supplied to the sliding surface of a port plate and the cylinder case 2, so that no tilting moment is acted to the cylinder case. Since, by employing such an arrangement, inclination of the cylinder case 2 can be reduced almost to zero, it is enabled to prevent lowering of the efficiency due to seizure, leakage of high- pressure fluid or by other reasons and hence to improve the self-priming performance of the pump motor.

摘要： PURPOSE:To discharge sludge efficiently from a hold by chopping soil tightly compacted with blades provided on a valve shaft for operating an opening-closing valve provided at an opening on the bottom of a ship leading to the lower portion of a hold. CONSTITUTION:A hold 12 is formed in a hull and a conical valve 3 is provided at the opening on the bottom leading to a hopper section 2 at the lower part thereof. The conical valve 3 located at the lower end of a valve shaft 4 is opened or closed with vertical movement of the valve shaft 4 while being turned by a driving mechanism 5. Chopping blades are provided on the valve shaft 4 by multistages each of which has three vanes projected in a radial manner. Sludge from the hold is lowered with the turning of the valve shaft 4 which enables efficient chopping of sludge with the blade 6.
